Cornulitida is an extinct order of encrusting animals from the Tentaculita class, which were common across the globe in the Ordovician to Devonian oceans, and survived until the Carboniferous.[1]

The organisms had shells, and were subject to predation by boring and other means from the Ordovician onwards. Many survived attacks by predators.[1]

Their affinity is unknown; they have been placed in many phyla, and have been considered worms, corals, molluscs and more.[1] They appear to be closely related to other taxa of uncertain affinity, including the microconchids, trypanoporids and tentaculitids.[1]
